Installation Notes(For Hydraulic Series)
Cautions
● Installation Notes (Cautions for Hydraulic Series)
1)Check the fluid to use
● Please use the appropriate fluid by referring to the Hydraulic Fluid List.
● If hydraulic oil with viscosity grade higher than ISO-VG-32 is used, action time would be longer. ● If using it at low temperature, action time will be longer because the viscosity of hydraulic oil becomes higher.
2)Procedure before Piping
● The pipeline, piping connector and fixture circuits should be
cleaned by thorough flushing.
● The dust and cutting chips in the circuit may lead to fluid
leakage and malfunction.
● Our products except some valves are not equipped with
protective function to prevent dust and cutting chips going
into the hydraulic system and pipeline.
3)Applying Sealing Tape
● Wrap with tape 1 to 2 times following the screwing direction.
● Pieces of the sealing tape can lead to air leaks and malfunction.
● In order to prevent a foreign substance from going into
the product during piping, it should be carefully cleaned.
4)Air Bleeding in the Hydraulic Circuit
● If the hydraulic circuit has excessive air, the action time may
become very long.
After installing the hydraulic circuit, or if the pump run out of oil,
be sure to bleed air by the following step.
① Reduce hydraulic supply pressure to less than 2MPa.
② Please loosen the cap nut of pipe fitting that is closest to
clamps・RA die lifters by one full turn.
③ Wiggle the pipeline to loosen the outlet of pipeline fitting.
The hydraulic fluid mixed with air comes out.
④ Tighten the cap nut after bleeding.
⑤ It is more effective to bleed air at the highest point inside
the circuit or at the end of the circuit.
5)Checking Looseness and Retightening
● At the beginning of the machine installation, the bolt/nut
For spring return single acting cylinders, restricting flow
during release can extremely slow down or disrupt release action.
The preferred method is to control the flow during the lock action
using a valve that has free-flow in the release direction.
It is also preferred to provide a flow control valve at each actuator.
Accelerated clamping speed by excessive hydraulic flow to
the cylinder may sustain damage. In this case add flow control to
regulate flow.
● Flow Control Circuit for Double Acting Cylinder
Flow control circuit for double acting cylinder should have meter-out
circuits for both the lock and release sides. Meter-in control can
have adverse effect by presence of air in the system.
【Meter-out Circuit】
【Meter-in Circuit】
In the case of meter-out circuit, the hydraulic circuit should
be designed with the following points.
① Single acting components should not be used in the same
flow control circuit as the double acting components.
The release action of the single acting cylinders may become
erratic or very slow.
Refer to the following circuit when both the single acting
cylinder and double acting cylinder are used together.
○ Separate the control circuit.
○ Reduce the influence of double acting cylinder control unit.
However, due to the back pressure in tank line, single action
cylinder is activated after double action cylinder works.
② In the case of meter-out circuit, the inner circuit pressure may
increase during the cylinder action because of the fluid supply.
The increase of the inner circuit pressure can be prevented by
reducing the supplied fluid beforehand via the flow control valve.
Especially when using sequence valve or pressure switches for
clamping detection. If the back pressure is more than the set
pressure then the system will not work as it is designed to.
